Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68442, here are decompositions:
- 5 + 68437 = 68442
- 43 + 68399 = 68442
- 53 + 68389 = 68442
- 71 + 68371 = 68442
- 113 + 68329 = 68442
- 131 + 68311 = 68442
- 163 + 68279 = 68442
- 181 + 68261 = 68442
Showing the first eight; more decompositions exist.
